Speed, Distance, Time Worksheet. Use * m/s, km/h, or mph. Calculate Speed R̅= P 1. A car travels a distance of 540km in 6 hours. Calculate the speed of the car. 2. John is a runner. He runs the 100m sprint in 20.0 s. Calculate the John’s speed. 3. Lauren walks 400 m in 125 s . Calculate Lauren’s average speed. 4.
Velocity has a magnitude (the speed) and also a direction (which way the object is moving). •A change in velocity can be a change in the object’s speed or direction of motion. •A speedometer doesn’t indicate direction, so it indicates instantaneous speed but not velocity.
Acceleration is a change in speed or velocity. Let us imagine that the car is initially travelling at 15 m/s, and that one second later it has reached 17 m/s, and that its speed increases by 2 m/s each second after that.
“Velocity” and “speed” are often used interchangeably in everyday speech, but in physics we distinguish between the two. Velocity is a vector, so it has both a magnitude and a direction, while speed is a scalar. Speed is the magnitude of the instantaneous velocity (see the next page). Let’s define average speed.
In this chapter, we study speed, velocity, and acceleration for motion in one-dimension. One dimensional motion is motion along a straight line, like the motion of a glider on an airtrack.
be able to solve problems on motion with constant velocity and constant acceleration, including problems involving several such stages understand what is meant by the terms average speed and average velocity .
Part 1 - Speed Calculations: Use the speed formula to calculate the answers to the following questions. Be sure to show your work for each problem (write the formula, numbers with correct units, and the answer with the correct units). 1. Calculate the speed for a car that went a distance of 125 kilometers in 2 hours time. Equation:
